AI 产品解读Chrome extension that bridges the Japanese e-Tax web application with a native Windows application and IC card reader for My Number card authentication and digital signing
Enables Japanese taxpayers to log into the government's e-Tax electronic tax filing system and digitally sign tax filings/applications using their My Number card and IC card reader through Chrome, which otherwise cannot directly access hardware card readers
User installs the extension and a companion native Windows app. When visiting e-Tax websites (login.e-tax.nta.go.jp, keisan.nta.go.jp, etc.), the content script injects hidden elements for communication. The web page dispatches custom events (NtaChromeLaunch) which the content script relays to the background script, which forwards messages to the native app via native messaging. The native app interfaces with the IC card reader to read the My Number card, perform authentication, and return signed data back through the chain.

- 目标用户
- Japanese individual taxpayers filing taxes electronically via e-Tax / Japanese tax professionals and accountants / Businesses using e-Tax for corporate tax filings / Users with My Number cards and IC card readers
- Chrome Web Store detail was unavailable (API error), so no store description or rating info could be cross-referenced
- Cannot verify the native Windows companion app (nta.chrome.ext) as it is distributed separately by the National Tax Agency
- Cannot confirm whether the extension works without the native companion app installed

- The extension is a bridge to Japan's e-Tax system (login.e-tax.nta.go.jp and related domains). Users must log in to e-Tax using a physical My Number card (マイナンバーカード) and IC card reader. The extension itself has no login UI or account system—it facilitates the connection between the e-Tax web app and a native Windows application that reads the card. The login is required at the destination service (e-Tax) to use the extension's core workflow.

全てがポンコツ。何度拡張機能をインストールすれば出来るようになるのでしょうか？競合ソフトが無いため、製作サイドはこちらのレビューやクレームに対して改善をすることも考えていないと思われます。技術とサービスの劣った国に生まれたことが悲しいです。
何回やっても、同じ。何度インストールすれば動くようになる？ ええ加減にせえよ！ 税金いらんのか!! 一つ、星つけたけど、つけへんかったら投稿でけへんからつけただけ ゼロ以外のナニモンでもない。 どこに金つことんねん こんだけ、書かれてまだそのままかい？
手間ばかりかかる、ばかばかしい
事前準備に手間がかかりすぎて使い物になりません。改善されることはないでしょうが…
ダメソフト いったいいつ直るのか
何回やらせるのか

何回クロームからインストールしてもダメなのは自分だけではないのですね。 ★マイナス５があればいいのに
